With up to 32 KB of on-chip flash memory, the R8C/33T microcontroller (MCU) group from Renesas features an on-chip Sensor Control Unit (SCU) for capacitive-touch applications. The MCUs incorporate 18 independent capacitive-touch channels and 4 KB of data flash memory with background operation (BGO).
They incorporate an R8C 16-bit CPU core, a data transfer controller (DTC), 8- and 16-bit timers, and up to 12 channels of analog-to-digital conversion. The devices support 1.8 V to 5.5 V operation and are packaged in a 32-pin, 7mm × 7mm LQFP.
